Title: Re: [ccp4bb] Post-translational modification induced strcture Collagen probably isn't a great example as hydroxylation of proline in collagen enhances the thermal stability of collagen, it doesn't really "induce" collagen structure, as unhydroxylated (pro-pro

Hi Miles - I would say a good example of that phenomenon is collagen, where hydroxylation of the prolyl residues alows the polypeptide to adopt its helical conformation. In that case it is the fact there is an electronegative substituent on the prolyl ring that biases it into a particular conforma

Dear All - Does anyone have some good examples where a post-translational modification has induced local structure? I'm particularly thinking of structure induced by the modification only and not something multi-step like a modification that recruits a cofactor that induces structure. Than
